Figure 59. Schematic diagram of switching circuit - front panel
In
Figure
59, SOURCE HI, SOURCE LO, SENSE HI and SENSE LO correspond to the front panel
input terminals of BT5321; K1, K2, K3 and K4 are relays, numbers 1~6 represent probe tips, and line
segments represent connected test cables.
1. For different test functions, it is necessary to set the relays to the corresponding state first:
